SUPPORT FOR ELECTRIC WIRES.

SPECIFICATION forming part of Letters Patent No. 433,896, dated August 5, 1890.

Application filed November 30, 1889. Serial No. 332,126. (No model.)

ductors, and is especially adapted to be used in connection with the trolley-wire of the overhead system of electric railways.

In accordance with our invention the trolley-wire hanger or supportis made as a clamp, preferably in two pieces or jaws, having suitable curved lugs or cars, which pass under and about the trolley-wire, so that when the said pieces or jaws are fastened together, as by screws, the trolley-wire rests upon a firm support and is firmly clamped between the said jaws, thereby preventing the trolleywire from falling at their points of suspension. The hanger or support is provided with a hooked arm or upright adapted to engage a span-wire, and the said hanger is secured in place upon the said span-wire, but insulated therefrom by disks of insulating material fastened to the span-wire.

Our invention therefore consists of a trolley-wire support or hanger composed of two pieces or jaws having lugs to extend under and embrace the trolleyewire, and lugs to prevent the said wire from lifting upward, and means to fasten the said jaws together to hold the wire between them, substantially as will be described.

Other features of our invention will be pointed out in the claims at the end of this specification.

Figure 1 represents a sufficient portion of a trolley-wire sustained byour improved hanger or support to enable our invention to be understood; Fig. 2, a side elevation, on an enlarged scale partially broken out, of the hanger or support shown in Fig. 1; Fig. 3, a top or plan view of the hanger or support shown in Fig. 2; Figs. 4 and 5, details to more clearly show the construction of the hanger or support, and Fig. 6 a detail to be referred to.

pieces or jaws to a, each provided with lugs or cars M, which extend under and support the trolley-wire a when the said pieces or jaws are fitted and secured together, as by screws to. The piece or jaw a is provided at its opposite ends with lugs a, between which and the car a of the said jaw the trolley-wire a is extended. the lugs at preventing the trolley-wire from being lifted upward.

The hanger or support may be provided, as herein shown, with an upright arm having at its end a hook I), which in practice is fitted upon the hub 19 of the disk b of insulation, the said disk and hub being provided with a slot 12 by which the said disk is placed upon the span-wire I). The hub 19' of the disk 11 as herein shown, has also mounted upon it a like slotted disk b and the disks 6 b are provided, as herein shown, on their outer side with extended hubs b, which are fastened to the span-wire b by set-screws b In practice the set-screws b arejunscrewed, so as to permit the disks b b to be turned so that the slots 19 of the said disks will register with the slot of the hook Z9, so that the hanger may be readily slipped upon or engage with the span-wire, and thereafter the disks b b may be turned so as to bring their slots out of line with the slot of the hook-as, for instance, into the position shown in Fig. 2, and secured in such position by the set-screws 11 It will thus be seen that the hanger is insulated from the span-wire and has a pivotal movement upon the same.

The trolley-wire is firmly clamped between the jaws a a of the hanger, and is secured positively without the use of solder, and is prevented from falling at the points of suspension.

We have herein shown one method of suspending the clamping-j aw from the span-wire, but we do not desire to limit ourselves to the particular manner shown, as thesaid clamping-jaws may be suspended in any other or usual manner.

We claim- 1. A trolley-Wire support or hanger composed of two pieces or jaws a a, having lugs a to extend under and embrace the trolley wire, and with lugs a to prevent the said The han er or su ,ort consists of two vided with lugs to extend underthe said trolley-wire, means to unite said jaws, and an in- 15 sulator interposed between the said jaws and the span-wire, substantially as described.

In testimony whereof we have signed our names to this specification in the presence of two subscribing witnesses.
